Our ship amid the ice of the Southern Ocean as we headed toward our morning destination. Adventure knows no bounds. Our ship has been exploring south of the Antarctic Circle for the past 48 hours. After awakening to a slice of blue sky and icebergs large enough to alter our course, our expedition headed to the historic Detaille Island. On shore, guests explored an abandoned hut filled with scientific remnants and other trinkets of everyday life in Antarctica. In the afternoon, we cruised through the calm, ice-filled water before stopping for a most necessary polar plunge. It’s difficult to understand just how far south we’ve gone and how remote the land is. There’s just a feeling inside that tells you that you’ve been to a special place. For over a decade Paul North has been exploring the marine ecosystems of our planet. Whereas most think of diving as a warm water activity, he has chosen the road less traveled–specializing in polar diving. This has provided many rare opportunities to dive and explore from the Arctic to Antarctica and many wondrous places in between. Based on the passage above, Could you paraphrase the section about Paul North's diving experiences in polar regions?

To sail from the east of North America to its western coast was not impossible in the nineteenth century, but sailors may well have wished it was.  The voyage required ships to brave the frigid waters between South America and Antarctica, whose treacherous depths claimed as many as fifteen thousand bodies.  This abode of ninety-foot waves and buffeting gales marked only the mid-point in a circuit of the Americas, and the men who survived that reckoning still faced several more weeks at sea.Understandably, the desire for a shortcut was strong.  Previous exploration had revealed no naturally occurring waterway through Central America, but what if such a passage could be built?  These considerations were the genesis of what would become the Panama Canal.The first to attempt such a feat were the French, under the leadership of Ferdinand de Lesseps.  Having formerly engineered the Suez Canal connecting the Mediterranean and Red Seas, Lesseps was a natural choice to head what was presumed to be a similar endeavor.  With the enthusiastic support of his country and the permission of the Colombian government (which controlled Panama at that time), Lesseps and his team began work in 1880, 11 years after the Suez Canal had been completed.However, the mountainous jungles and swamps of Panama proved a pernicious contrast to the flat sands of Egypt.  Equipment toppled down hillsides or was swallowed into the mud, while frequent rains washed excavated dirt mounds back into the pits from which they had been extracted.  More devastating was the human toll.  Living conditions were squalid and miserable, as workers were ravaged by rampant yellow fever and malaria.  Over twenty thousand lives were lost, with no end in sight to the scourge of disease or to the faltering project.  Ultimately, the construction company went bankrupt, some of its members were imprisoned, and the elderly Lesseps died.With the failure of the French, the stage was set for the United States to try its hand.  Some American engineers recommended that the canal should be built through Nicaragua instead of Panama; although the former country was much wider, the terrain was significantly more hospitable.  An additional drawback to choosing Panama was that the Colombian government would not agree to let the U.S. control the canal once it was built.  Nonetheless, the U.S. decided to build in Panama.  Shortly thereafter, Panamanian dissident Manuel Amador led a rebellion against the Colombian government, while a U.S. warship happened to be sailing off the coast.  Victory was swift; as writer Janet Pascal notes: "The entire revolution lasted only a few hours.  Only one shopkeeper and a donkey were killed."  Afterward, newly independent Panama granted construction rights and control of the future canal to the U.S.Unfortunately, the U.S. claimed the French's abandoned equipment and facilities while failing to address their logistical difficulties and incidence of disease.  After a year of futility, wiser minds devised a new course.  Acting on the uncommon but accurate belief that mosquitoes spread malaria and yellow fever, Americans exterminated those pests and thus the maladies they caused.  In conjunction with new living facilities and improved transportation, this action provided the ability to sustain a healthy workforce and build the canal based on proper planning.The project spanned the American presidencies of Theodore Roosevelt, William Howard Taft, and Woodrow Wilson, reaching completion in 1914.  Traversing the breadth of Panama and incorporating a series of locks to raise and lower ships to different elevations, the Panama Canal finally made it possible to sail from the Atlantic Ocean to the Pacific without circumnavigating South America.  It remains in use to this day, more than a century after its construction.Passage Title: The Panama Canal Question 1If the passage description of the Panamanian revolution against Colombia (Paragraph 5) is accurate, which of the following would NOT be a reasonable assumption?A.The Panamanians resented Colombia for allowing the French to build in their countryB.Some Colombian soldiers were sympathetic to Amador's revolutionC.The Colombian government recognized the potential for United States military interventionD.The United States favored Panamanian independence from Colombia

"The team of explorers embarked on a daring expedition to Antarctica, a frozen world of untouched beauty and extreme challenges. Their mission was to study the effects of climate change on the region's delicate ecosystems. For weeks, they braved freezing temperatures, blizzards, and isolation, collecting data that would help scientists better understand the planet's changing climate. As they witnessed the breathtaking landscapes and the resilience of Antarctic life, they were reminded of the importance of preserving our planet for future generations."What was the exact purpose of the explorers' expedition to Antarctica?They were studying the effects of climate change.They were exploring Antarctica for scientific geography. .They were studying cold temperatures.They were studying the biodiversity of arctic ecosystems

Antarctica is located at the South Pole. It is the fifth-largest continent on Earth. It is as big as the United States and Mexico combined. Antarctic ice contains 70 percent of the world's fresh water. It also contains 90 percent of the world's ice. Antarctic ice can be as thick as two miles (3.2 kilometers). Though Antarctica is covered by miles of snow and ice, it hardly ever snows. It is too frigid for rainfall. Antarctica is a dry land surrounded by oceans.Do It!Antarctica has an unusual _________.Press enter to interact with the item, and press tab button or down arrow until reaching the Submit button once the item is selectedA historyB governmentC climateD language
